        Do you carry the gasket for this thermostat if so what is the part#?

        • We do not have a replacement gasket for installation. We recommend contact Mishimoto or Mopar.

            Noticed Difference Right Away

            Just had this thermostat installed today. I could tell the difference right away. It drives like a new oil change but the oil wasn't changed. Can't wait to try it on the trail.
